TANK FOR HYDROCARBON-BURNERS.

SPECIFICATION forming part of Letters Patent No. 496,661, dated May 2,1893.

Application filed september 19, 1892. Serial No. 446,260. (No model.)

ing drawings, making part of this specifica-' tion.

My invention relates to an improvement in tanks for hydrocarbon burners,which consists in providing devices by which the tempera ture of thehydrocarbon to be consumed may be raised, and to a limitedextent'vaporized in the tank, to produce pressure by which the fluid isdriven from the tank to the burner with such force as to supply therequired amount to the burner, and to obviate the necessity of an airblast.

The object of my invention is to provide a burner of great power of usein assaying ores, also for use in laboratories, dental offices and forjewelers, which will operate for a number of hours, consecutively,inexpensively and of itself.

With these ends in view my invention relates to certain features ofconstruction and combination of parts as will be hereinafter de scribedand pointed out in the claims.

The drawing is a side elevation, partly sectional of a hydrocarbon tankillustrating my invention.

A, indicates the tank which may be made of any suitable material and ofany desired dimensions to contain a given amount of gasoline or othersuitable hydrocarbons, having at its bottom portion a through pipe B,provided with apertures a by which the fluid may enter the pipe withoutsediment, so liable to be found in such fluids and so fatal to theoperation of burners suitable for the uses hereinbefore referred to. t

0, represents a burner which may be of the form shown or of any of thewell known and approved generator vapor burners, and b is a valve bywhich the supply of hydrocarbon to the burner is regulated.

I have for the purpose of this application shown the supply-pipe B,extended across and out from opposite sides of the tank A, for thepurpose of heating two furnaces, but

as the capacity of the hereinafter described devices to supply thepressure as well as the fluid is unlimited. Many pipes may radiate fromsaid tank to as many furnaces, all of which maybe attended by one personwho may at the same time assay several samples of ore.

The particular feature of my invention relates to the provision of anoutside tank jacket D, which consists of a cylindrical portion placedabout and spaced from the tank A as shown, the bottom of the cylinderperforated to pass over the tank, to which it is secured, either withsolder or rivets, the top of the said jacket to project a distance abovethe top portion of the tank as shown, the two parts secured in positionat the top portion by the stays c. Pipese and f project upwardly fromthe top portion of the tank A, as shown, the former having an inletthrough which the hydrocarbon is supplied, said pipe 6 having a turnvalve 9 to close said pipe, and the latter having a key, or pet-cock hthrough which the air or gas may escape while filling. A small burner E,is placed under the jacket as shown receiving its supply of gasolinefrom the pipe B.

In operation the tank A, is filled with gasoline or other lighthydrocarbon, and the jacket filled with water about and over the top ofthe tank. The burner E is lighted, the flame directed against the bottomportion of the jacket will raise the temperature of the water in thejacket and about the tank to a desired degree of temperature indicatedby a thermometer by which the gasoline is warmed and vaporized toproduce a pressure in the tank by which the gasoline is driven to theburner with great force, by which a greater volume of heat may beproduced and uniformly maintained and in every way giving a betterresult, and at less cost. The cutaway portion j shows an interiorportion of the tank A, and the cutaway portion m and a show interiorportions of the jacket.

The tank may be scaffolded as shown in the drawing or placed upon atable adapted to be raised or lowered by devices similar to those usedto raise the table in vertical drill presses. Having thus fullydescribed the nature and object of my invention, what I claim as new,

and desire to secure by Letters Patent, is-

I a supply pipe projecting from the top of said tank, a valve to closesaid pipe, an air or gas escape pipe, a cock for closing it, a pipe atin communication with said tank and burners B and C, the latter of whichis arranged to direct its flame against the water jacket.

In testimony whereof I have hereunto set my hand this 27th day ofAugust, A. D. 1892.
